Or whatever Duo are calling themselves these days!
I haven't been a fan of Duos selection for a while. I like a slim high heel which they just don't seem to want to do anymore. So, if there are any other skinny calved (calfed?) people out there who are looking for knee high boots that aren't Duo... have a look at Slim Calf Boots.com
They did come from America so they did take a while and I had to pay an extortionate amount of import tax on them... but I'm genuinely a bit in love and wanted to share the joy.
The quality is excellent, they are comfy enough to wear all day, they are warm and they fit wonderfully.
